How it works

How to get a second opinion

  1. Upload your schedule

    Use your schedule of values as it is. The SOV coder can add OED codes to messy rows.

  2. Run the open models

    Run hurricane, earthquake, flood and wildfire models on the same locations.

  3. Compare

    See average annual loss and 1-in-100 losses next to your broker’s figures.

Why it helps

What you get

Your own locations

Results are based on your own buildings and values.

The model and data behind each result

Every result shows the model and data behind it, so you can explain it to your board.

Reproducible results

Running the same inputs next year gives the same result, so if a number changes, you can see whether your locations, the data or the model version changed.
